Sometimes you will get a message about irsync_pristine failing, or that "irsync_dirty" is being tried; this is normal.

If the update halts (for instance, if you lose your network connection in the middle) you will be returned to the Terminal prompt. You can repeat the command to resume the update where it stopped:

olpc-update 767

4. Reboot after you see the "Update Succeeded!" message.

At the end of the upgrade, you will see "Installing update in...." and "Update Succeeded!"; you are halfway done. Type reboot from the terminal.

5. Connect to the Internet again.

As soon as you reboot, you will see a bar at the top of the screen that says "Software Update" with options "Cancel" / "Later" / "Check now"... and you will not have most of your old activities available from your Home view. Get online before choosing Check now.

6. Download and update activities.

Choose Check now from the options at the top of your Home view. If you don't see these option, you can launch it from the Control Panel's Software Update feature. The Control Panel is an option on the hover menu at the center of your Home view.

Your XO will check online for new activities and updates. Click "Install selected" once it is done to update everything. By default, the activities checked are any already on your machine and those included on G1G1 2008 builds.

c) choose the Refresh button, wait for the activity list to refresh, and Install selected to download them.

These changes should take effect without a reboot.

Congratulations, you've upgraded!

Upgrading offline

This process takes 10 minutes once you have downloaded the files onto a USB key.

You can use another computer that is connected to the internet (a desktop at home, a computer lab, etc.) and a USB storage device to upgrade your XO. This process will cmopletely erase ALL files on your XO.

Make sure your XO is plugged in and has its battery in.

Back up any files or Journal entries on your XO that you want to keep.

This helps ensure the process is not interrupted in the middle.

Get an empty USB stick with at least 500MB of space.

The USB stick does not have to be completely empty. However, avoid using the same USB stick for this and other types of OLPC backups.

Download the following files to your stick. Do not open or unzip the files.

Hold down all four gamepad keys (on the right side of the screen, above the power button) and then turn on the XO. Keep holding the gamepad keys until the message "Release the game key to continue" appears on the screen.

Release the game keys and wait for the reflash to complete.

You should see a grid of black boxes appear on your screen, and then fill with color. Your XO is now reflashing. It will take 8-10 minutes and your XO should automatically show a 'complete' message and reboot when it is done.

Reboot if it didn't happen automatically, and wait for the firmware to update.

This happens the next time you reboot, and should take 1 minute. It will not proceed unless your battery is in and your laptop plugged in. The XO will reboot automatically once more after this.

Your update is done! Explore your new Home view (the available activities are now laid out in a circle around the central XO, and active activities appear in the top of the frame) and make sure that your favorite activities are installed.

If you need to install new activities, you can do so via the new Control Panel (see above).
